I now have another payment proof from Opini. Once again there has been a payment of $14.70 deposited into my PayPal account with no questions asked and no troubles or delays. Opini continues to be a paying and trustworthy survey site for me so far.
I wish that there were more surveys from this site and it, of course would be wonderful to collect even a small amount from referrals, but I am taking this site as it comes for the moment. Not the greatest site out there, but with so few survey sites to use in New Zealand, this is a great one to add to your list of survey sites to use. Very few surveys are offset by the lowest cash out rate I have seen: $15.00.
